Description
Given that sin A=-3/5 and the terminal side of angle A lies in the third quadrant and cos B=5/13 and the terminal side of angle B lies in the fourth quadrant, find:
a) Cos A
b) Sin 2A
c) sec^2 B
d) Cos(A-B)
User generated content is uploaded by users for the purposes of learning and should be used following Studypool's honor code & terms of service.
Explanation & Answer
Cos A = -4/5
Sin 2A = -6/5 * -4/5 = 24/25
sec^2 B = 169/25
Cos (A-B) = -4/13 + 36/65 = (-20+36)/65 = 16/65
Please let me know if you have any questions and best me if you are satisfactory.

Pittsburgh Pirates Dataset in SPSS
Perform a multiple linear regression on the Pittsburgh Pirates Dataset in SPSS (you should use the dataset provided here and should not create any new variables in SPSS). Try to select the variables that you think will affect the attendance and that make sense. The goal of the regression is to get the adjusted R Square as high as possible (but be careful not to run into multicollinearity issues). Run various linear regressions and compare the adjusted R Squares with each other. Report the results for the model with the highest R Square.Prepare a two-page report in which you report the "coefficients" table that SPSS provides in the output and the "model summary" table which includes the adjusted R Square. Report which steps you have taken to arrive at the final results. Did you run into any problems and/or challenges? Report them! If you excluded certain variables because of outliers or multicollinearity problems, please explain. Submit your report before the end of Week 10.Hint 1: Use attendance as the dependent variable. Select your independent variables carefully. Hint 2: If you include the days of the week and/or the months of the year as dependent variables, make sure you exclude one day of the week and one month of the year from your independent variables (if you do not do that you may run into problems with the full rank assumption; SPSS will automatically exclude any variables that will cause full rank problems, but it is better to exclude them yourself)

We have to provide sufficient answers to support our knowledge. the book for the class is Behavioral Sciences STAT - With Access 2ND 15Author: Heiman, GaryISBN-13: 978-1-285-45814-4ISBN-10: 1-285-45814-1Edition/Copyright: 2ND 15Publisher: Wadsworth, Incwill copy and paste assignment below:Scenario: Imagine you are a researcher who is interested in studying whether sleep deprivation leads to increased reaction times (i.e., being slower) when driving. You randomly select a sample of 30 licensed drivers. Fifteen participants are randomly assigned to get 5 hours of sleep for three consecutive nights. The other 15 participants are randomly assigned to get 8 hours of sleep for three consecutive nights. For the purposes of this Assignment, assume that all participants sleep exactly the required amounts. After the third night, all participants take a driving simulation test that measures their reaction times.You can find the data for this Assignment in the Weekly Data Set forum. By Day 7To complete this Assignment, submit a response to each of the following. Use SPSS to determine if amount of sleep is related to reaction time.Explain whether the researcher should use an independent-samples t-test or a related-samples t-test for this scenario. Provide a rationale for your decision.Identify the independent variable and dependent variable.Knowing the researcher believes that people who sleep less will have slower reaction times, state the null hypothesis and alternate hypothesis in words (not formulas).Explain whether the researcher should use a one-tailed test or two-tailed test and why.Identify the obtained t value for this data set using SPSS and report it in your answer document.State the degrees of freedom and explain how you calculated it by hand.Identify the p value using SPSS and report it in your answer document.Explain whether the researcher should retain or reject the null hypothesis. Provide a rationale for your decision. Are the results statistically significant?Explain what the researcher can conclude about the relationship between amount of sleep and reaction times.Be sure to fully explain the rationale for your answer to each question, including evidence from the text and Learning Resources.Provide an APA reference list.Submit three documents for grading:Your text (Word) document with your answers and explanations to the assignment questions, your SPSS Data file, and your SPSS Output file.DATA SET BELOW:

Quality at A1 Hotels
A1 Hotels operates luxury hotels throughout the world. Recently, motivated by some incidents that appeared in the news, they have been concerned about the quality of service. The company has been giving the following survey to its clients after their stay:How would you rate the quality of your room? Select one.Good(G), Poor(P)How would you rate the quality of your food? Select one.Good(G), Poor(P)How would you rate the quality of your service? Select one.Good (G), Poor(P)Any customer who answered “Poor” to at least one of the three questions up above is considered to be “dissatisfied.” Traditionally, 40% of customers have been dissatisfied.A1 Hotels would like to study customer satisfaction. Therefore, 200 survey responses were recently chosen at random for analysis. The complete data set is in the file named Hotels.Managerial ReportPrepare a report (see below) for A1 Hotels that summarizes your assessment of customer satisfaction. Be sure to include the following seven items in your report.To summarize the data, compute the proportion of all clients thatAnswered “Poor” to room quality.Answered “Poor” to food quality.Answered “Poor” to service quality.Develop the 92% confidence interval for the proportion of all recent clients that were “dissatisfied.” What is the margin of error? What are the lower (or left) and upper (or right) endpoints of the confidence interval? Interpret your results.Develop the 92% confidence interval for the proportion of all recent clients who answered “Poor” to room quality. What is the margin of error?

Use α = 0.08. Do not forget to include the correctly worded hypotheses and show all the steps required to conduct the hypothesis test.What advice would you give to A1 Hotels based upon your analysis of the data?
